How do I: Read from a Merged Configuration Tree?

[astorm]

Suggestion for

http://devdocs.magento.com/guides/v2.0/howdoi/bk-how-do-i.html

How do I, as a module developer, read data from a merged configuration tree? (the merged events.xml, module.xml, di.xml, etc)

How do I, as a module developer, create my own configuration file that other modules can merge in app/etc/?

After discussing internally, we decided this is not a good how-to topic. We have an internal issue on something similar, MAGETWO-38492.

We expect to have some kind of UI that shows this in a future release.

@astorm every configuration type is represented by separate object (example: Magento\Framework\Event\Config for events.xml). You can get merged configuration from those objects. Do you want to have the full list of such objects documented?

Does this presentation cover the topics you want to be described?
